💡 Hint

Common Mistakes

Using 'Yes' or 'No' instead of boolean values.

Leaving the value as 'False' which disables metrics.

Setting enabled = True activates Prometheus metrics in Airflow.

medium

Complete the code to set the Prometheus metrics port in Airflow's configuration.

Apache Airflow

[metrics]
port = [1]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using ports like 8080 or 5000 which are not default for Prometheus.

Choosing a random port number.

Port 9090 is the default port for Prometheus metrics in Airflow.

💡 Hint

Common Mistakes

Using 'start' or 'launch' which are not valid Airflow CLI commands.

Typing 'execute' instead of 'serve'.

The correct Airflow CLI command to start the metrics server is airflow metrics serve.

4fill in blank

hard

Fill both blanks to create a Prometheus scrape configuration for Airflow metrics.

Apache Airflow

- job_name: 'airflow'
  static_configs:
    - targets: ['[1]:[2]']

Drag options to blanks, or click blank then click option'

Alocalhost

💡 Hint

Common Mistakes

Using the wrong port like 8080.

Using a hostname that does not resolve to the metrics server.

The scrape target should be localhost:9090 to collect Airflow metrics locally on the default port.

5fill in blank

hard

Fill all three blanks to define a Prometheus alert rule for Airflow task failures.

Apache Airflow

groups:
- name: airflow_alerts
  rules:
  - alert: AirflowTaskFailure
    expr: airflow_task_failed_total[1] > [2]
    for: [3]m

Drag options to blanks, or click blank then click option'

A{job="airflow"}

B5

C10

D{job="scheduler"}

Attempts:

💡 Hint

Common Mistakes

Using the wrong job label like 'scheduler'.

Setting too low or too high thresholds without reason.

The alert triggers if the total failed tasks metric for the Airflow job exceeds 5 for 10 minutes.
